[0003] Neurodegenerative diseases are caused by the progressive loss of neuronal structure or cellular function and subsequent cell death in neuronal tissue, a process known as neurodegeneration. Neurodegeneration can progress through various components or levels of neural circuits, resulting in characteristic clinical symptoms such as Alzheimer's disease, Parkinson's disease, multiple system atrophy, amyotrophic lateral sclerosis, Huntington's disease, multiple sclerosis, prion diseases, and other human diseases.
[0004] As a non-limiting example, Alzheimer's disease (AD) is the most common neurodegenerative disease and the leading cause of dementia in elderly individuals. Senile plaques composed of amyloid beta (Aβ) fibrils, neurofibrillary tangles composed of aggregated tau protein, and neuronal dysplasia and neuronal loss characterize AD pathology and constitute the diagnostic biomarker profile for AD (see Jack CR, Jr. et al. (2018) Alzheimers Dement 14:535-562). The earliest pathological changes may occur more than 20 years before the onset of clinical symptoms of AD (see Jack CR, Jr. et al. Alzheimer's Disease Neuroimaging I (2009) Brain 132:1355-1365; Braak H, et al. (2011) J Neuropathol Exp Neurol 70:960-969; Bateman RJ et al. (2012) N Engl J Med 367:795-804; Gordon BA et al. (2018) Lancet Neurol 17:241-250; Barthelemy NR et al. (2020) Nat Med 26:398-407; Quiroz YT et al. (2020) Lancet Neurol 19:513-521), suggesting opportunities for early intervention and disease-modifying therapies.
[0005] AD susceptibility is influenced by common genetic variants, among which the APOE allele variant ε4 (APOE4) stands out due to its large effect size and significant enrichment within patient populations. Compared to the risk-neutral ε3 / ε3 genotype, inheritance of one or two ε4 alleles increases AD risk by 3-4-fold or 9-15-fold, respectively (see Farrer LA, et al. (1997) JAMA 278:1349-1356; Genin E, et al. (2011) Mol Psychiatry 16:903-907; Neu SC, et al. (2017) JAMA Neurol 74:1178-1189). Furthermore, compared with ε4 noncarriers, inheritance of one ε4 allele decreases the age at onset of AD by 2-8 years, and inheritance of two ε4 alleles decreases the age at onset by 5-16 years (see Corder EH, et al. (1993) Science 261:921-923. Sando SB, et al. (2008) BMC Neurol 8:9). In a meta-analysis of 38 paired case-control samples across multiple ethnic groups, the mean allele frequency of ε4 was found to be 38% in AD patients compared with 14% in cognitively healthy individuals (Alzgene. APOE_2 / 3 / 4. http: / / www.alzgene.org / meta.asp?geneID=83, updated 2010).
[0006] The human APOE protein consists of a receptor-binding domain in the amino-terminal domain and a lipid-binding domain in the carboxy-terminal domain. Nascent APOE protein is secreted by cells and associates with the cell surface ATP-binding cassette transporters ABCA1 and ABCG1. This allows cholesterol and phospholipids to be transferred to nascent APOE to form lipoprotein particles (see Wahrle SE, et al. (2004) J Biol Chem 279:40987-40993).
[0007] In the healthy brain, APOE is primarily expressed in astrocytes, microglia, vascular wall cells, and choroid plexus cells; however, under pathological or injury conditions, APOE expression is significantly upregulated in myeloid cells, including microglia and macrophages (see Xu Q, et al. (2006) J Neurosci 26:4985-4994; Yamazaki et al. (2019) Nat Rev Neurol 15(9):501-518). APOE plays physiological and pathophysiological roles, shuttling cholesterol and other lipids between various brain cell types via cell surface APOE receptors (see Hauser PS, et al. (2011) Prog Lipid Res 50:62-74; Yamazaki et al. (2019) Nat Rev Neurol 15(9):501-518).
[0008] The common APOE ε4 and ε3 allele variants encode the APOE4 and APOE3 protein isoforms, respectively. APOE4 differs from APOE3 at amino acid position 112 (APOE3: Cys112, APOE4: Arg112). Despite this difference in only a single amino acid substitution, APOE4 exerts numerous effects on the pathogenesis of AD (see Yamazaki Y, et al. (2019) Nat Rev Neurol 15:501-518). This is often characterized as a toxic gain-of-function APOE effect. The most prominent feature of such a toxic gain-of-function effect is that APOE4 reduces Aβ clearance and promotes Aβ aggregation, which correlates with the clinical phenotype of accelerated Aβ plaque deposition in ε4 allele carriers, with deposition most accelerated in ε4 / ε4 homozygous carriers. In both humans and animal models, APOE4 is associated with loss of blood-brain barrier (BBB) integrity (see Ishii M and Iadecola C (2020) Nature 581:31-32; Montagne A et al. (2020) Nature 581:71-76; Jackson RJ, et al. (2022) Brain 145:3582-3593). Additionally, the ε4 allele is also associated with high levels of TAR DNA-binding protein 43 (TDP-43) pathology in the brains of individuals with AD (see Vossel KA, et al. (2013) Neurocase 19:295-301; Josephs KA, et al. (2017) Lancet Neurol 16:917-924; Yang HS, et al. (2018) Lancet Neurol 17:773-781).Furthermore, the ε4 allele increases the risk of developing Lewy body dementia (see Tsuang D et al. (2013) JAMA Neurol 70:223-228, Bras J et al. (2014) Hum Mol Genet 23:6139-6146, Guerreiro R et al. (2018) Lancet Neurol 17:64-74) and Parkinson's disease dementia (PDD) (see Huang X, et al. (2006) Arch Neurol 63:189-193, Irwin DJ, et al. (2012) Ann Neurol 72:587-598, Tsuang D et al. (2013) JAMA Neurol 70:223-228, Tropea TF, et al. (2018) Mov Disord 33:289-297).
[0009] Experimental studies have shown that APOE4 exacerbates tau pathology and tau-mediated neurodegeneration in animal models. Furthermore, APOE4 induces effects that can be characterized as the decline in physiological and pathophysiological functions of APOE, including microglial responsiveness, neuroinflammation, energy metabolism, cholesterol and lipid transport and homeostasis, synaptic integrity and plasticity, glucose metabolism, and neurovascular integrity and function (see Liu CC, et al. Nat Rev Neurol 9:106-118; Yamazaki Y, et al. (2019) Nat Rev Neurol 15:501-518; Martens YA, et al. (2022) Neuron 110:1304-1317). Furthermore, APOE4 disrupts physiological functions of APOE, such as microglial responsiveness, neuroinflammation, energy metabolism, cholesterol and lipid transport and homeostasis, synaptic integrity and plasticity, glucose metabolism, and neurovascular integrity and function (see Liu CC, et al. Nat Rev Neurol 9:106-118; Yamazaki Y, et al. (2019) Nat Rev Neurol 15:501-518; Martens YA, et al. (2022) Neuron 110:1304-1317).
[0010] Preclinical data are available demonstrating that certain APOE-targeted ASOs administered via intracerebroventricular (icv) injection early in the pathological onset of AD in mouse models can be effective in reducing brain amyloid burden. Most importantly, this intervention prevents the development of tau pathology in AD mice, reduces neurite malformation, and reduces levels of neurofilament light chain (NfL), a marker of neuronal damage, regardless of amyloid pathology or the timing of ASO administration relative to the onset of AD pathology. Additional readouts confirmed that icv delivery of APOE ASO prevented tau pathology and associated neurodegeneration, maintained synaptic density (reduced synaptic loss), and reduced the release of neuroinflammatory markers and pro-inflammatory cytokines in the brain, without affecting lipid levels in the liver and plasma (see Huynh TV, et al. (2017) Neuron 96:1013-1023 e1014; Litvinchuk A. et al. (2021) Ann Neurol 89:952-966). Recent data utilizing biochemical in vitro and in vivo methodologies in rodent disease models suggest that certain APOE-targeting monoclonal antibodies (α-APOE antibodies), which are selective for non-lipidated aggregated APOE, can preferentially bind to APOE in amyloid plaques. These antibodies have a similar mode of action and efficacy compared to Aβ-targeting monoclonal antibodies (anti-Aβ antibodies), which also bind to Aβ aggregates and reduce Aβ aggregates via a microglial-mediated clearance mechanism (see Liao F et al. (2018) J Clin Invest 128:2144-2155). Furthermore, certain α-APOE antibodies appear to specifically bind to dense-core plaques, while other anti-Aβ antibodies bind to widespread amyloid, including that deposited in cerebral blood vessels in cerebral amyloid angiopathy (CAA). Mechanistically, α-APOE antibodies specifically targeting plaques initially enhance glial activation, thereby persistently recruiting microglia and improving vascular function, whereas less specific anti-Aβ antibodies targeting vascular amyloid induce chronic perivascular astrogliosis and persistence of CAA pathology (see Xiong M, et al. (2021) Sci Transl Med 13, 581). The resulting neurovascular pathology and damage observed in animal models is consistent with amyloid-associated imaging abnormalities (ARIA-E & ARIA-H pathology) observed in human subjects treated with anti-Aβ antibodies (see Sperling RA et al. (2011) Alzheimers Dement 7:367-385, 2011; Salloway S, et al. (2022) JAMA Neurol 79:13-21). A related dataset demonstrates that after sustained treatment with α-APOE antibodies in AD mouse models, tau seeding, spreading, and resulting dysplasia in neurites is reduced, consistent with a reduction in overall individual amyloid burden (see Gratuze M, Jiang H, Wang C, Xiong M, Bao X, Holtzman DM (2022) Ann Neurol 91:847-852).Although the efficacy of amyloid- and APOE-targeted molecules in reducing amyloid plaques is similar, APOE-targeted molecules appear to offer an advantage by mediating additional beneficial effects on vascular phenotype while also reducing tau seeding, nucleic acid pathology, and tau markers (see Liao F et al. (2018) J Clin Invest 128:2144-2155; Xiong M, et al. (2021) Sci Transl Med 13,581; Gratuze M, et al. (2022) Ann Neurol 91:847-852). Unfortunately, antibody therapies, such as α-APOE antibodies, are limited to extracellular effects due to the potential for insufficient penetration into brain tissue due to the antibody's large molecular weight, short retention in the brain after direct administration, and short duration of effect. Therefore, additional agents and methods for reducing APOE expression are needed. [Prior art documents] [Non-patent literature]

[0041] [Figure 1] These are phase-contrast microscopy images showing that some ASOs (e.g., S1038 (SEQ ID NO: 24)) cause abnormal morphological cell changes in HEP3B cells, while other ASOs cause morphology equivalent to that of untreated controls. All cells were cultured for 48 hours with or without ASO. (A) is a microscopy image showing HEP3B cells not treated with ASO ("untreated control"). (B) is a microscopy image showing that HEP3B cells treated with ASO S1038 (12.5 nM (SEQ ID NO: 24)) exhibit abnormal epithelial cell morphology (e.g., loss of confluency, dense pyknotic nuclei), indicating cytotoxicity and cell death, compared to untreated HEP3B cells. (C) is a microscopy image showing that HEP3B cells treated with ASO S1094 (12.5 nM (SEQ ID NO: 80)) exhibit morphology and confluency equivalent to that of untreated HEP3B cells. This indicates that ASO S1094 (SEQ ID NO: 80) is non-toxic to HEP3B cells. DETAILED DESCRIPTION OF THE INVENTION
[0042] Mutation and expression of apolipoprotein E (APOE) are highly correlated with human diseases, particularly neurological disorders (e.g., Alzheimer's disease (AD), dementia with Lewy bodies, and Parkinson's disease). AD susceptibility is influenced by common genetic variants, among which the APOE allelic variant ε4 (APOE4) stands out due to its large effect size and significant enrichment within patient populations. Compared to the risk-neutral ε3 / ε3 genotype, inheritance of one or two ε4 alleles increases AD risk by 3-4-fold or 9-15-fold, respectively (see Farrer LA, et al. (1997) JAMA 278:1349-1356; Genin E, et al. (2011) Mol Psychiatry 16:903-907; Neu SC, et al. (2017) JAMA Neurol 74:1178-1189). Therefore, APOE has been investigated as a potential target for treating neurological diseases and other diseases in which APOE may play a role in disease pathology.Unfortunately, antibody therapy such as α-APOE antibody may have poor penetration into brain tissue due to the large molecular weight of antibody, short retention in the brain after direct administration, and short duration of effect, and is limited to extracellular effects.Therefore, there is a need for additional drugs and methods for reducing APOE expression.

[0060] Treatment method The present disclosure further relates to methods of using the oligonucleotides and pharmaceutically related salts disclosed herein for the treatment of diseases and disorders (e.g., human diseases and disorders, neurodegenerative diseases). The mode of action of oligonucleotides such as those described herein differs from the mode of action of antibodies or small molecules, and oligonucleotides can be used to treat, for example, They offer significant advantages in terms of (i) penetration into tissues, such as brain tissue, where their size is substantially smaller than that of antibodies, resulting in better penetration than antibodies and the potential for direct delivery to the brain (e.g., Noguchi Y, et al. (2017) MAbs 9:1210-1215, Pizzo ME, et al. (2018) J Physiol 596:445-475); (ii) retention in the brain and extended duration of effect after direct administration; (iii) blocking multiple target functions and activities, respectively; (iv) combination with other oligonucleotides or with antibodies or small molecules; and (v) inhibition of intracellular effects that are inaccessible to antibodies or cannot be inhibited via small molecules.
[0061] Taking AD or neurodegenerative diseases in general together, there is a clear need for effective therapeutic agents that can target the underlying pathobiological mechanisms. Counteracting the pathogenic gain-of-function toxic effects of APOE variants may be a therapeutic approach for patients with APOE ε4 who have been diagnosed with AD, DLB, PDD (see Li Y, Macyczko JR, Liu CC, Bu G (2022) Neurobiol Aging 115:20-28), or any other human patients or diseases associated with APOE dysregulation. Specifically, therapeutic effects can be achieved by suppressing the expression of mRNA encoding APOE. Alternatively, therapeutic effects can be achieved by suppressing the expression of pre-mRNA encoding APOE.
[0062] Two competing technologies have been primarily described for the specific suppression of mRNA expression: siRNA and antisense oligonucleotides (ASOs). siRNA targets mRNA in the cytoplasm. In contrast, RNase H-dependent ASOs target pre-mRNA in the nucleus. This allows ASOs to target intronic regions inaccessible to siRNA, significantly expanding the target space for ASOs. Furthermore, due to their double-stranded nature, siRNAs do not cross cell membranes by themselves, and a delivery system is required for their activity in vitro and in vivo. While there are siRNA delivery systems that efficiently deliver siRNA to liver cells in vivo, no system currently exists that can deliver siRNA outside liver tissue in vivo with sufficient efficacy. In contrast, modified ASOs can enter many cell types in vitro in sufficient quantities without transfection or delivery methods, resulting in potent and sequence-specific target knockdown. In vivo, naked, unconjugated ASOs achieve target knockdown in several different relevant tissues after systemic administration. Following direct administration, ASOs achieve potent and durable target knockdown in the central nervous system (CNS), indicating the strong potential of ASOs for the treatment of CNS diseases such as neurodegenerative disorders (see Geary RS et al. (2015) Adv Drug Deliv Rev 87:46-51).

[0080] Modified oligonucleotides complementary to APOE nucleic acids can be designed and tested for their effect on APOE mRNA in vitro. The modified oligonucleotides can be tested in a series of experiments under similar culture conditions.
[0081] The modified oligonucleotides in the table below can be uniformly modified oligonucleotides. The length of the oligonucleotides can be 21 nucleobases, and each nucleoside can have a 2'-substitution or modification described herein.
[0082] The modified oligonucleotides in Tables 1 and 2 below can be designed as gapmers. The gapmer can be 20 nucleosides in length, with a central gap segment containing 10 2'-deoxynucleosides flanked at both its 5' and 3' ends by wing segments, each containing 5 nucleosides (5-10-5 gapmer (except for ASO S1095 (SEQ ID NO: 81) which is a 4-10-4 gapmer), Table 1). Each nucleoside in the 5' wing segment and each nucleoside in the 3' wing segment contains a 2'-modification. The 2'-modification is a 2'-methoxyethyl (e.g., 2'-MOE) modification.
[0083] In embodiments, each internucleoside linkage is a phosphorothioate internucleoside linkage. [Table 1-1] [Table 1-2] [Table 1-3] [Table 1-4] [Table 1-5] [Table 1-6] [Table 1-7] [Table 1-8] [Table 1-9] [Table 2-1] [Table 2-2]

[0085] The modified oligonucleotides in Tables 3 and 4 below can be designed as gapmers.

Each nucleoside in the 5' wing segment and each nucleoside in the 3' wing segment contains a locked nucleic acid (LNA) modification.
[0086] In embodiments, each internucleoside linkage is a phosphorothioate internucleoside linkage. [Table 3-1] [Table 3-2] [Table 3-3] [Table 3-4] [Table 3-5] [Table 3-6] [Table 3-7] [Table 4-1] [Table 4-2] [Table 5]
[0087] Example 1: Evaluation of Targeted Knockdown Efficacy and Toxicity of APOE-Specific ASOs in HEP3B Cells A detailed description of the methods used in this example can be found in the supplemental experimental section below. Briefly, the knockdown efficacy of 79 APOE-specific ASOs was evaluated in human HEP3B cells in vitro. Cells were treated with APOE-specific ASOs (12.5 nM) or non-silencing control oligonucleotides (12.5 nM) by transfecting them with LIPOFECTAMINE™ 2000 (THERMO FISHER SCIENTIFIC INC., 11668030). Forty-eight hours after treatment, cells were lysed. APOE and HPRT1 mRNA levels were analyzed using quantitative real-time polymerase chain reaction (qPCR), and APOE expression values were normalized to the value of the endogenous housekeeping control gene HPRT1. The results of ASO-mediated APOE and HRPT1 knockdown in HEP3B cells are shown in Table 1 as residual APOE or HRPT1 mRNA expression compared with the non-silencing control ASO as a reference sample (normalized to 1).
[0088] Treating HEP3B cells with ASOs S1043, S1042, S1044, S1041, and S1025 (SEQ ID NOS: 11, 27-30) achieved >80% knockdown (represented by a residual APOE mRNA expression of <0.2 compared to cells treated with a non-targeting control ASO) (see Table 1). Of note, not all screened ASOs were highly efficient at downregulating APOE mRNA. Some ASOs, such as ASOs S1017, S1027, S1033, S1018, and S1065 (SEQ ID NOS: 3, 4, 13, 19, and 51), downregulated target gene expression by approximately 30% compared to non-targeting control ASOs. This indicates that our screening experiments identified target mRNA knockdown efficacies ranging from approximately 30% to approximately 90% of control levels among the 79 ASOs tested.
[0089] Changes in the expression levels of the HPRT1 housekeeping gene in response to ASO treatment (i.e., transfection) were used as a proxy to identify ASOs that exhibited cytotoxicity under the experimental conditions used. The use of the HPRT1 readout as an approximation of cytotoxicity was validated by live-cell imaging of HEP3B cell cultures. Figures 1A, 1B, and 1C show that cultures treated with ASO S1094 (SEQ ID NO: 80), which does not downregulate HPRT1 housekeeping gene expression (see Table 1), were nontoxic (Figure 1C), as determined by imaging, with confluency and cell morphology comparable to that of untreated cell cultures (Figure 1A). In contrast, cell cultures treated with ASOs that downregulate HPRT1 housekeeping gene expression (e.g., ASO S1038 (SEQ ID NO: 24)) (see Table 1) were not confluent with large numbers of cells but instead displayed abnormal morphology and density, pyknotic nuclei, indicative of cytotoxicity and cell death (Figure 1B). Since both ASOs S1094 (SEQ ID NO: 80) and S1038 (SEQ ID NO: 24) have comparable efficacy in downregulating the target gene APOE (see Table 1, approximately 70 to approximately 80% downregulation), the observed morphological changes are consistent with toxicity and HPRT1 mRNA is not associated with APOE downregulation.
[0090] Based on the observation that downregulation of the HPRT1 housekeeping gene coincided with confluency and cell morphology (e.g., indicators of microscopic cytotoxicity), the 79 screened molecules were further classified into two categories. Under the test conditions, ASOs that reduced HPRT1 mRNA by more than 20% in HEP3B cells were considered cytotoxic, while ASOs that modulated HPRT1 mRNA by less than 20% were considered non-toxic. Table 1 summarizes the HPRT1 mRNA expression levels after ASO transfection into HEP3B cells. ASOs S1024, S1088, S1047, S1077, and S1059 (SEQ ID NOs: 10, 33, 45, 63, and 74) resulted in robust APOE target inhibition (e.g., APOE mRNA knockdown) of >70% without any cytotoxic effects on HPRT1 housekeeping gene expression. In contrast, ASOs S1043, S1042, S1044, S1041, and S1025 (SEQ ID NOs: 11, 27, 28, 29, and 30) are highly effective in downregulating APOE mRNA but exhibit cytotoxic effects, reducing expression of the HPRT1 housekeeping gene by approximately 25% to approximately 40% in HEP3B cells.
[0091] In summary, we identified 37 ASOs (see Table 2) that down-regulate APOE target gene mRNA without causing significant cytotoxicity under our experimental conditions (e.g., no change in confluency or morphology compared to non-silencing controls) (see Figures 1A and 1C). Additional assays may be used to demonstrate the potency and efficacy and other properties of these molecules in vitro and in vivo.
[0092] Experimental Supplementary Section: This section provides details about the specific techniques and reagents used in the above example(s). Preparation of antisense oligonucleotides (ASOs): ASOs were synthesized by Integrated DNA Technologies (IDT) using their standard desalting process.
[0093] Cell culture: HEP3B cells (ATCC HB-8064) were maintained at 37°C and 5% CO in growth medium containing EMEM (ATCC 30-2003) with 10% FBS (VWR 97068-085) and 1% penicillin and 1% streptomycin (Pen-Strep) (THERMO FISHER SCIENTIFIC INC. 15140122) and passaged using 0.25% trypsin-EDTA (THERMO FISHER SCIENTIFIC INC. 25200-114) as a cell dissociation reagent. For ASO screening, HEP3B cells were plated at 15,000 cells per well of a 96-well plate in growth medium without Pen-Strep.
[0094] ASO transfection using Lipofectamine 2000: Each ASO was prepared as a 5 μM stock solution in ULTRAPURE™ DNase / RNase-Free Distilled Water (THERMO FISHER INC., 10977023) and stored at -80°C until use. Transfections were performed in triplicate culture wells as biological triplicates, with a final ASO concentration of 12.5 nM per well of a 96-well plate. The day after cell plating, the medium in each culture well was replaced with 90 μl of growth medium without Pen-Strep. For each ASO, the 5 μM stock solution (5 μM) was prediluted to 1.25 μM using ULTRAPURE™ DNase / RNase-Free Distilled Water. The prediluted ASO was further diluted to 0.25 μM using OPTI-MEM™ (THERMO FISHER INC., 31985062). LIPOFECTAMINE™ 2000 (THERMO FISHER SCIENTIFIC INC., 11668030) was prediluted to 6% (v / v) with OPTI-MEM™ and incubated for 5 minutes. Equal volumes (v / v) of 0.25 μM ASO in OPTI-MEM™ and 6% (v / v) LIPOFECTAMINE™ 2000 (THERMO FISHER SCIENTIFIC INC., 11668030) in OPTI-MEM™ were mixed and incubated for 10 minutes. 10 μl of the mixture was added to each culture well for a total volume of 100 μl per well. For the non-transfected control, all of the above steps were repeated except that 0.25 μM ASO in OPTI-MEM™ was replaced with OPTI-MEM™ alone. Cell confluency, as a surrogate observation marker for monitoring cell health and potential toxicity of ASO treatment, was determined by live-cell imaging of each well at 0, 24, and 48 hours post-transfection using the INCUCYTE® platform (SARTORIUS AG).
[0095] Cell lysis and quantitative RT-PCR: 48 hours after transfection, cells were lysed according to the instructions in the CELLS-TO-CT™ 1-step TAQMAN™ Kit (THERMO FISHER SCIENTIFIC, INC. A25602). 50 μl of RNA lysate was harvested per culture well and stored at -80°C until RT-qPCR. One-step RT-qPCR was performed in a 384-well plate. Each reaction consisted of 10 μl of a mixture containing 2.5 μl of TAQMAN™ 1-Step qRT-PCR Mix (THERMO FISHER SCIENTIFIC, INC.), 0.5 μl of APOE TAQMAN™ Assay FAM-MGB (Hs00171168_ml) (THERMO FISHER SCIENTIFIC, INC. 4331182), 0.5 μl of HPRT1 TAQMAN™ Assay VIC-MGB (Hs02800695_ml) (THERMO FISHER SCIENTIFIC, INC. 4448489), 1 μl of RNA lysate, and 5.5 μl of UltraPure™ DNase / RNase-Free Distilled Water. The thermal cycling method was as follows: 50°C for 5 minutes, 95°C for 20 seconds, followed by 40 cycles of i) 95°C for 3 seconds, ii) 60°C for 30 seconds. Cycle threshold (Ct) values were analyzed using the delta-delta Ct method, with HRPT1 as the housekeeping gene and either a non-silencing control ASO or a non-transfection control as the reference sample. Variation between culture plates was controlled by including a non-transfection control, a non-silencing control ASO, and a positive control (S1087, SEQ ID NO: 73) identified from a pilot screen for APOE knockdown in the transfection scheme of each culture plate.Normalization between culture plates was performed using the "percentage of positive controls" method as described in Malo N, Hanley JA, Cerquozzi S, Pelletier J, Nadon R (2006) Statistical practice in high-throughput screening data analysis. Nat Biotechnol 24:167-175.
[0096] Example 2: Evaluation of Targeted Knockdown Efficacy and Toxicity of APOE Pre-mRNA-Specific ASOs in HEP3B Cells A detailed description of the methods used in this example can be found in the supplemental experimental section below. Unless otherwise noted, all other methods used in this example were similar to those presented in Example 1 above. Briefly, the knockdown efficacy of 147 ASOs targeting APOE pre-mRNA was evaluated in human HEP3B cells in vitro. Cells were treated by delivering APOE pre-mRNA-targeting ASOs (5 μM) or the non-silencing control oligonucleotide S1250 (5 μM, SEQ ID NO: 83) without a carrier (gymnotic). Cells were lysed 72 hours after treatment. APOE and HPRT1 mRNA levels were analyzed using quantitative real-time polymerase chain reaction (qPCR). The results of APOE and HRPT1 knockdown by APOE pre-mRNA-targeting ASOs in HEP3B cells are shown in Table 3 as residual APOE or HRPT1 mRNA expression compared with the non-silencing control ASO as a reference sample (normalized to 1).

[0098] Experimental Supplementary Section: This section describes the reagents, protocols, and details regarding the specific techniques used in Example 2.
[0099] Treatment with LNA-modified ASOs: Each ASO was prepared as a 500 μM stock solution in ULTRAPURE™ DNase / RNase-Free Distilled Water (THERMO FISHER INC., 10977023) and stored at -80°C until use. Treatment was performed in triplicate culture wells as biological triplicates, with a final ASO concentration of 5 μM per well of a 96-well plate. For each ASO, the 500 μM stock solution was prediluted to 250 μM using ULTRAPURE™ DNase / RNase-Free Distilled Water. One hour after cell plating, 2 μl of prediluted ASO was added to each culture well. Cell confluency, as a surrogate marker for monitoring cell health and potential toxicity of ASO treatment, was determined by live-cell imaging of each well 72 hours after treatment using the INCUCYTE® platform (SARTORIUS AG).
[0100] Cell lysis and quantitative RT-PCR: 72 hours after treatment (gymnotic delivery), cells were lysed according to the instructions in the CELLS-TO-CT™ 1-step TAQMAN™ Kit (THERMO FISHER SCIENTIFIC, INC. A25602). RNA lysates were harvested at 50 μl per culture well and stored at -80°C until RT-qPCR. One-step RT-qPCR was performed in a 384-well plate. Each reaction consisted of 10 μl of a mixture containing 2.5 μl of TAQMAN™ 1-Step qRT-PCR Mix (THERMO FISHER SCIENTIFIC, INC.), 0.5 μl of APOE TAQMAN™ Assay FAM-MGB (Hs00171168_ml) (THERMO FISHER SCIENTIFIC, INC. 4331182), 0.5 μl of HPRT1 TAQMAN™ Assay VICMGB (Hs02800695_ml) (THERMO FISHER SCIENTIFIC, INC. 4448489), 1 μl of RNA lysate, and 5.5 μl of UltraPure™ DNase / RNase-Free Distilled Water. The thermal cycling method was as follows: 50°C for 5 minutes, 95°C for 20 seconds, followed by 40 cycles of i) 95°C for 3 seconds, ii) 60°C for 30 seconds. Cycle threshold values (Ct) were analyzed using the delta-delta Ct method, with HRPT1 as the housekeeping gene and either a non-silencing control ASO or treatment control as the reference sample. Variation between culture plates was controlled by including a non-silencing control ASO (S1250 (SEQ ID NO: 83)) and an assay control ASO for APOE knockdown (S1248 (SEQ ID NO: 228)) in each culture plate. Normalization between culture plates was performed using the "percentage of positive controls" method, as described in Malo N, Hanley JA, Cerquozzi S, Pelletier J, Nadon R (2006) Statistical practice in high-throughput screening data analysis.

In describing and claiming the present invention, the following terminology will be used.
[0102] It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
[0103] The articles "a" and "an" are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, "an element" means one element or more than one element.
[0104] As used herein, "about" when referring to measurable values such as amounts, lengths of time, and the like, is meant to encompass variations of 20% or 10%, more preferably 5%, even more preferably 1%, and even more preferably 0.1% from the specified value, and thus variations are applicable in the practice of the disclosed methods.
[0105] "Effective amount" or "therapeutically effective amount" are used interchangeably herein and refer to the amount of a compound, formulation, substance, or composition described herein that is effective in achieving a particular biological result or provides a therapeutic or prophylactic benefit.
[0106] "Encoding" refers to the inherent property of a specific nucleotide sequence in a polynucleotide (such as a gene, cDNA, or mRNA) to serve as a template for the synthesis of other polymers and macromolecules in biological processes that have either a defined nucleotide sequence (i.e., rRNA, tRNA, and mRNA) or a defined amino acid sequence and the biological properties that result therefrom. Thus, a gene encodes a protein when that protein is produced in a cell or other biological system by transcription and translation of the mRNA corresponding to that gene. Both the coding strand (whose nucleotide sequence is identical to the mRNA sequence, usually that presented in a sequence listing), and the non-coding strand (used as a template for transcription of the gene or cDNA) can be referred to as encoding a protein or other product of that gene or cDNA.
[0107] Unless otherwise specified, a "nucleotide sequence encoding an amino acid sequence" includes all nucleotide sequences that are degenerate versions of each other and that encode the same amino acid sequence. The phrase nucleotide sequence encoding a protein or RNA can also include introns, to the extent that versions of the nucleotide sequence that encode the protein may contain intron(s).
[0108] As used herein, the terms "peptide," "polypeptide," and "protein" are used interchangeably and refer to compounds composed of amino acid residues covalently linked by peptide bonds. A protein or peptide must contain at least two amino acids, and there is no limit to the maximum number of amino acids that can comprise a protein or peptide sequence. A polypeptide includes any peptide or protein containing two or more amino acids connected to each other by peptide bonds. As used herein, the term refers to both short chains, commonly referred to in the art as peptides, oligopeptides, and oligomers, and longer chains, generally referred to in the art as proteins, of which there are many types. Among other things, "polypeptide" includes, for example, biologically active fragments, substantially homologous polypeptides, oligopeptides, homodimers, heterodimers, polypeptide variants, modified polypeptides, derivatives, analogs, and fusion proteins. A polypeptide can be a natural peptide, a recombinant peptide, a synthetic peptide, or a combination thereof.
[0109] The term "subject" is intended to include a living organism (e.g., a mammal) in which an immune response can be elicited. As used herein, a "subject" or "patient" can be a human or a non-human mammal. Non-human mammals include, for example, livestock and pets, such as ovine, bovine, porcine, canine, feline, and murine mammals. Preferably, the subject is a human.
